DETAILED DESCRIPTION OF THE INVENTION

The following is clearly and completely describes of the technicalsolutions in the embodiments of the present invention. Apparently, thedescribed embodiments are merely some but not all embodiments of thepresent invention. All other embodiments obtained by a person who isskilled in the art based on the embodiments of the present inventionwithout creative efforts shall fall within the protection scope of thepresent invention.

As shown in FIG. 1-2, the embodiment of the present invention includes:an anti-blocking type ultra-low water land submersible amphibious pumpincluding: an outer shell body 1, a motor 2, a water tank 3, a motorhousing 4, a flow guiding disc 5, a cover plate 6, a flow guidingchamber 7, an impeller 8, a suction nozzle 9, and a base 10, said motor2 and said water tank 3 are disposed in the outer shell body 1, themotor 2 is disposed in the motor housing 4, a half body of the motorhousing 4 is accommodated in said water tank 3, and the flowing guidingdisc 5 is fixed on the cover plate 6 to form a flow guiding chamber 7,the cover plate 6 is fixed on the motor housing 4, an impeller 8 isdisposed at the end of the motor shaft, the impeller 8 is accommodatedin the flow guiding chamber 7, the outer surface of the flow guidingdisc 5 is provided with a support, a suction nozzle 9 is arranged on thesupport, and the base 10 covers the suction nozzle 9 and is fixed to thebottom of the outer shell body 1.

Wherein, the impeller 8 is an enclosed impeller and the flow guidingdisc is a dual-flow spiral flow guiding disc.

Further, a half-opened base 11 is disposed on the base 10, and anopen-close hinge is disposed between the half-opened base 11 and thebase 10. A position of the half-opened base 11 corresponds to thesuction nozzle 9, and both half-opened base 11 and the base 10 areprovided with filter meshes.

Further, a dual-purpose handle 12 is further provided on the upper endof the outer shell body 1, and the gripping portion of the dual-purposehandle 12 extends out laterally and formed a supporting foot 13.

Further, a water outlet 14 communicating with the water tank 3 isdisposed on a side surface of outer shell body 1, an air exhaustingnozzle 15 is disposed on the wall of the water outlet 14, and a steelball 16 is disposed in the air exhausting nozzle 15.

The dual-flow spiral flow guiding disc 5 adopts a two water-ejectiveArchimedes spiral design so as to improve the hydraulic efficiency. Whenused as a submersible pump, the filter closed and acts as a base 10 tosupport the pump body and filters impurities; when used as a groundpump, the filter window opens and expose the pipe fitting. When used asa ground pump, the dual purpose handle 12 can act as a standing foot 13.When the water pump is working, the impeller 8 discharges the water intothe water tank 3 and the water surrounds and cools the housing of themotor 2 and then discharge the water outside the pump, by using thisprocess to cool the motor 2. When the pump used as a submersible pump,the water suction port is downwards disposed so that the water level canbe pumped to a very low level. When used as a ground pump, it lay onaside and the suction pipe can be used as a jointing to a pipeline.

In summary, the present invention provides an anti-blocking typeultra-low water land submersible amphibious pump, which has thefunctions of a ground pump and a submersible pump, realizes submersibleand land amphibious functions, and has the advantages of convenient andflexible to be moved, and can better expand the adaptation range of thepump.
